Öğe Mapping the salinity of common soil groups of siverek district of sanliurfa province by geographical information systems (GIS)(Parlar Scientific Publications, 2020) Karaduman, Hamza; Yalcin, MehmetThis study aims to determine the salinity status of the common soil groups of Siverek district of Sanliurfa by mapping with Geographic Information Systems (GIS).For this purpose, a total of 76 soil samples were taken from 38 different points in the depths of 0-20 and 20-40 cm, representing the common soil groups of Siverek district of Sanliurfa province. pH, cation exchange capacity (CEC) and exchangeable cation (DK) values were determined in order to determine some properties of soils.In order to determine the salinity status of soils, properties such as total salt, salinity class, sodium adsorption rate (SAR), changeable sodium percentage (ESP) and soluble cations (Na, Ca and Mg) were determined. According to the reaseacrh results results of analysis to determine the salinity of soils, it was determined that pH values were between 6.91-7.98, total salt contents 0.02-0.13%, SAR values 0.023-0.044; ESP values 0.35-2.96, Na content of soluble 0.019-0.034, soluble Ca content 0.018-0.245 and soluble Mg content 0.037-0.113. In addition, by applying the ESP¬ SAR regression relationship, it was shown that soils tend to alkalize towards the lower layers.The salinity values obtained from the study were transferred to Geographical Information Systems (GIS) and interpolated by Kriging method and salinity map of the study area was created. As a result of the study carried out in the soil of the study area, it was determined that all of the common soil groups of Siverek region were classified as unsalted and no problems were encountered in terms of salinity status of soils. © 2020 Parlar Scientific Publications.

Bu amaçla Şanlıurfa ili Siverek bölgesi yaygın toprak serilerini temsil edecek şekilde 0-20 ve 20-40 cm derinliklerinden ve 38 ayrı noktadan olmak üzere toplamda 76 toprak örneği alınmıştır. Alınan toprak örneklerinde toprakların bazı fiziksel ve kimyasal özelliklerini belirlemek için pH, bünye, katyon değişim kapasitesi (KDK), değişebilir katyonlar (DK), kireç ve organik madde değerleri belirlenmiştir. Toprakların tuzluluk durumunun belirlenmesi için ise toplam tuz, tuzluluk sınıfı, sodyum adsorbsiyon oranı (SAR), değişebilir sodyum yüzdesi (ESP), çözülebilir katyonlar (Na, Ca ve Mg) gibi özellikler belirlenmiştir. Araştırma sonuçlarına göre; toprakların pH içerikleri 6.91-7.98; kil içerikleri % 24.32-67.76; kum içerikleri % 2.40-62.96; silt içerikleri % 6.00-68.72; kireç içerikleri % 0.38-14.55; organik madde içerikleri % 1.11-3.35 arasında bulunmuştur. Toprakların tuzluluk durumunu belirlemek için yapılan analiz sonuçlarına göre; toplam tuz içerikleri % 0.02-0.13; SAR değerleri 0.023-0.044; ESP değerleri 0.35-2.96; çözülebilir Na içeriği 0.019-0.034; çözülebilir Ca içeriği 0.018-0.245 ve çözülebilir Mg içeriği ise 0.037-0.113 arasında belirlenmiştir. Sonuç olarak, çalışma alanı topraklarında yapılan çalışma sonucunda Siverek bölgesi yaygın toprak serilerinin tamamının tuzsuz sınıfına girdiği ve toprakların tuzluluk durumu bakımından hiç bir problem yaşamadığı belirlenmiştir.
